Microorganisms, Medicines, and Bioremediation.
Since the discovery of penicillin in the 1920s, biotechnology has played a key role in the development of medicines. Producing penicillin The first effective antibiotic was penicillin, produced by a mould called Penicillium notatum. The yield of penicillin from this mould was very small. Commercial production of the drug in the quantities needed to treat…

Microorganisms and Biotechnology
The earliest recorded use of microorganisms by people was around 6000 BC when the Sumerians and Babylonians were using yeast to make beer. By 4000 BC the Egyptians were using yeast to make their bread rise. These are all examples of the development and use of biotechnology over several millennia. Defining biotechnology Biotechnology involves applying…

Understanding Natural and Artificial Cloning in Plants
Asexual reproduction is a form of cloning and it results in offspring produced by mitosis known as clones. Clones are usually genetically identical to both the parent organism and to each other. Natural cloning Vegetative propagation, or natural cloning, occurs in many species of flowering plants. A structure forms which develops into a fully differentiated…

Genetic Engineering, Gene Technology and Ethics
DNA sequencing and proteomics provide us with a detailed understanding of an organism’s genetic instructions. Advances in these technologies and molecular biotechnology techniques mean it is now possible to manipulate an organism’s genome to achieve a desired outcome. This manipulation of the genome is called genetic engineering. The basic principles of genetic engineering involve isolating…

The Science and Principle of Taste, Smell, and pH
The Science and Principle of Taste, Smell, and pH Some sensory cells, called chemoreceptors, contain membrane proteins that can bind to particular chemicals or ligands in the extracellular fluid. In response to this chemical interaction, the membrane of the sensory neuron becomes depolarized and produces action potentials. Chemoreceptors are used in the senses of taste…

Enlighten Knowledge note; The Lymphatic System.
The Lymphatic System. The lymphatic system, which is closely associated with the cardiovascular system, has four main functions that contribute to homeostasis: Lymphatic capillaries absorb excess tissue fluid and return it to the bloodstream. In the small intestines, lymphatic capillaries called lacteals absorb fats in the form of lipoproteins and transport them to the bloodstream.…

Animal Tissues; Types and Their Functions.
Animal Tissues; Types and Their Functions. Cells form a working animal body through their emergent properties, which arise from successive levels of structural and functional organization. Cells are organized into tissues, groups of cells with a similar appearance and a common function. Different types of tissues are further organized into functional units called organs. (The…
